Nonalcoholic fatty liver disease (NAFLD) is the hepatic manifestation of the metabolic syndrome and can vary from benign steatosis to end-stage liver disease. The pathogenesis of non-alcoholic steatohepatitis (NASH) is currently thought to involve a multiple-hit process with the first hit being the accumulation of liver fat which is followed by the development of necroinflammation and fibrosis....

Non-alcoholic steatohepatitis (NASH) is characterized by the presence of steatosis, inflammation and hepatocyte injury and constitutes hepatic manifestation of the metabolic syndrome. The pathogenesis of NASH is complex and implicates cross-talk between different metabolically active sites, such as liver and adipose tissue. Obesity is considered a chronic low-grade inflammatory state and the li...

Nonalcoholic steatohepatitis (NASH) and alcoholic liver disease have similar pathological features. Because CYP2E1 plays a key role in alcoholic liver disease with its ability to stimulate lipid peroxidation, we tested the proposal that CYP2E1 could also be a factor in the development of NASH. In a dietary model - mice fed a methionine- and choline-deficient (MCD) diet - liver injury was associ...

Non-alcoholic steatohepatitis (NASH) is the more aggressive form of non-alcoholic fatty liver disease (NAFLD). NASH can progress to hepatic fibrosis, cirrhosis, portal hypertension and primary liver cancer. Therapy is evolving with a substantial number of trials of promising new agents now in progress. In this article however, we will examine data for several older forms of therapy which have b...

Primary liver cancer (hepatocellular carcinoma, HCC) is the fifth most common cancer in men and the seventh in women worldwide. It rarely occurs before the age of 40 years and reaches its peak incidence at approximatively 70 years of age. Major risk factors for HCC include: infection with hepatitis B (HBV) or hepatitis C (HCV), alcoholic liver disease, non-alcoholic fatty liver disease and less...

Mitochondrial dysfunction plays a crucial role in the development of non-alcoholic steatohepatitis (NASH). However, the regulator of mitochondrial dysfunction in the pathogenesis of NASH is still largely unclear. CXCR3 is an essential pro-inflammatory factor in chronic liver diseases. We explored the significance of CXCR3 in regulating mitochondrial function during NASH development in animal mo...

Amphiregulin (AR) involvement in liver fibrogenesis and hepatic stellate cells (HSC) regulation is under study. Non-alcoholic fatty liver disease (NAFLD) and its more severe form non-alcoholic steatohepatitis (NASH) may progress to cirrhosis and hepatocellular cancer (HCC). Our aim was to investigate ex vivo the effect of AR on human primary HSC (hHSC) and verify in vivo the relevance of AR in ...

AIMS/INTRODUCTION We reinvestigated the clinical usefulness of the modified NAFIC scoring system, modified by changing the weightage assigned to the fasting serum insulin level based on the importance of hyperinsulinemia in the pathogenesis of non-alcoholic steatohepatitis (NASH), in Japanese patients with non-alcoholic fatty liver disease (NAFLD) who had undergone liver biopsy. MATERIALS AND...

ABSTRACT Non-alcoholic fatty liver disease is a very common medical condition, driven by combination of genetic and lifestyle factors, ultimately producing severe chronic increased cardiovascular risk. Most people are asymptomatic for long time, their daily life unaffected, leading to difficulty in identifying managing who slowly progress non-alcoholic steatohepatitis (NASH), NASH-cirrhosis, ev...

European and American guidelines recommend surveillance for hepatocellular carcinoma (HCC) by performing ultrasonography on a six-month basis on an at risk population, defined by presence of cirrhosis. HCC, due to non-alcoholic steatohepatitis (NASH), is rising. Patients with NASH have a high risk of developing HCC and, therefore, have to be enrolled in a screening program. One of the challenge...
